Book Description
Industry and government are increasingly reliant on an intelligent – or ‘smart’ – and interconnected computer infrastructure, but the reality is that it is extremely difficult to provide full cyber defense and/or intrusion prevention for the smart networks that connect intelligent industrial and logistics modules, since the more intelligent the systems are, the more vulnerable they become. This book presents papers from the NATO Advanced Research Workshop (ARW) on Cyber Defence in Industry 4.0 Systems and Related Logistics and IT Infrastructures, held in Jyvaskyla, Finland, in October 2017. The main focus of the 11 papers included here is the creation and implementation of cyber systems and cyber platforms capable of providing enhanced cyber security and interoperability for smart IT infrastructure. Topics covered include: smart intrusion prevention; adaptive cyber defense; smart recovery of systems; and the smart monitoring, control and management of Industry 4.0 complexes and related logistics systems such as robotic equipment, logistics modules, units and technologic equipment, as well as their IT infrastructure.

Book Description
Le travail présenté dans cette thèse constitue une contribution à la modélisation et à l’analyse de performances des systèmes logistiques à l’aide d’un nouveau modèle de réseaux de Pétri stochastiques. Il s’agit d’une problématique au centre des préoccupations actuelles des entreprises industrielles mais très peu abordée par la communauté des réseaux de Pétri. Dans ce travail, nous développons un nouveau modèle de réseaux de Pétri dits réseaux de Pétri lots déterministes et stochastiques (BDSPNs) capable de supporter les caractéristiques essentielles des systèmes logistiques et plus généralement des systèmes à événements discrets. Ils sont particulièrement adaptés pour la modélisation de flux évoluant en quantités discrètes (lots de différentes tailles et variables) et ils permettent de prendre en compte des activités plus spécifiques telles que les commandes des clients, l’approvisionnement des stocks, la production et la livraison en mode lot. Les BDSPNs permettent par leur formalisme graphique et mathématique de capturer pertinemment et simplement cet aspect lot omniprésent dans différentes locations de ces systèmes et qui s’implique très considérablement dans leur comportement et par conséquent dans leur analyse. Nos travaux portent à la fois sur la théorie d’un nouveau modèle, sur ses techniques d’analyse et sur ses applications aux systèmes logistiques. Ainsi, les résultats obtenus et les applications effectuées font des BDSPNs un outil de modélisation performant aussi bien pour l’analyse que pour la simulation

Book Description
This work presents a comprehensive model of supply chain management. Experienced executives from 20 companies clearly define supply chain management, identifying those factors that contribute to its effective implementation. They provide practical guidelines on how companies can manage supply chains, addressing the role of all the traditional business functions in supply chain management and suggest how the adoption of a supply chain management approach can affect business strategy and corporate performance.

Book Description
This book summarizes current knowledge regarding the theory of estimation for semiparametric models with missing data, in an organized and comprehensive manner. It starts with the study of semiparametric methods when there are no missing data. The description of the theory of estimation for semiparametric models is both rigorous and intuitive, relying on geometric ideas to reinforce the intuition and understanding of the theory. These methods are then applied to problems with missing, censored, and coarsened data with the goal of deriving estimators that are as robust and efficient as possible.

Book Description
One critical barrier leading to successful implementation of flexible manufacturing and related automated systems is the ever-increasing complexity of their modeling, analysis, simulation, and control. Research and development over the last three decades has provided new theory and graphical tools based on Petri nets and related concepts for the design of such systems. The purpose of this book is to introduce a set of Petri-net-based tools and methods to address a variety of problems associated with the design and implementation of flexible manufacturing systems (FMSs), with several implementation examples.There are three ways this book will directly benefit readers. First, the book will allow engineers and managers who are responsible for the design and implementation of modern manufacturing systems to evaluate Petri nets for applications in their work. Second, it will provide sufficient breadth and depth to allow development of Petri-net-based industrial applications. Third, it will allow the basic Petri net material to be taught to industrial practitioners, students, and academic researchers much more efficiently. This will foster further research and applications of Petri nets in aiding the successful implementation of advanced manufacturing systems.

Book Description
Multistage stochastic optimization problems appear in many ways in finance, insurance, energy production and trading, logistics and transportation, among other areas. They describe decision situations under uncertainty and with a longer planning horizon. This book contains a comprehensive treatment of today’s state of the art in multistage stochastic optimization. It covers the mathematical backgrounds of approximation theory as well as numerous practical algorithms and examples for the generation and handling of scenario trees. A special emphasis is put on estimation and bounding of the modeling error using novel distance concepts, on time consistency and the role of model ambiguity in the decision process. An extensive treatment of examples from electricity production, asset liability management and inventory control concludes the book.
